The conclusion? The current $20 price could be halved, if you’re lucky. Again, remember there is no guarantee that prices will fall your way immediately. You might have to wait for a while.

Also, remember that this search engine doesn’t only work for books, but anything you purchase on Amazon.

I would also encourage you to first click through Amazon links provided by blog writers like yours truly. The Amazon Associates program gives us up to a 7% kickback at no cost to you. It doesn’t matter what you end up buying (sinks, lingere, or laptops), so long as you first reach Amazon by clicking one of our links.

Certain readers of Cosmos the in Lost have taken an active approach of first clicking through my links before making any purchase. Their actions have helped to keep this blog going with some serious pocket change.
